查看更多>>摘要：Recently,interventional ablation techniques have gained prominence in tumor treatment guidelines and complement traditional approaches,such as surgery,chemotherapy,and radiotherapy.Conventional ablation techniques,such as microwave,radiofrequency,and cryoablation,have been used;however,they have certain limitations,including the risk of damaging surrounding normal tissues and the heat sink effect caused by tumor blood flow.1 Irreversible electroporation(IRE),an ablation technology independent of thermal energy,is a promising alternative.2 Clinical studies have demonstrated IRE's efficacy in treating tumors,such as pancreatic and liver tumors.3 Recent research has shown that IRE can elicit specific anti-tumor immune responses in the body.5 IRE also plays a crucial role in eliminating residual tumor cells postoperatively and preventing tumor recurrence.

查看更多>>摘要：Percutaneous abscess drainage is a procedure commonly performed by interventional radiologists to provide source control on infections using CT or ultrasound guidance.The interventionalist has many different sizes and shapes of catheters to treat abscesses of varying sizes and locations,but the general approach to each abscess is similar:provide a percutaneous route for purulence,bacteria,necrotic tissue,and other debris to escape the body.While generally considered a low-risk procedure,adverse events can occur due to operator error or other means.We present a unique case of an abscess drain placed into a right upper quadrant ab-scess that formed following laparoscopic cholecystectomy that perforated and entered the colon.Astute physicians,both in the emergency department and the radiology reading room,were able to rapidly rule out more common post-operative complications and make the correct diagnosis,likely preventing dangerous sequelae from developing in this patient.
